Self-reported intake misses foods. 1–80% of the time (Whitton et al., Adv Nutr 2022). Per 100 g: 91 kcal, 19.4 g protein, 0.9 g fat. Lean whitefish blends into recall — weigh rather than remember.
How should I track Perch, mixed species, raw?
Perch, mixed species, raw is a good source of protein. For the most accurate tracking of Perch, mixed species, raw, weigh it raw and boneless. Fish loses 15–25% of its weight during cooking as water evaporates (USDA cooking yield data). If you are using canned fish, the drained weight is what matters — the difference between oil-packed and water-packed can be 40–80 calories per can. A quick drain-and-weigh habit saves you from hidden calories. Also keep in mind that smoked or cured fish has different values than fresh due to moisture loss and added salt.
